For the purpose mentioned, use is made of: a series oi' pressure 4devices encircling .the block, and exerting when used in a building or alongl the said line laees in a natural broken condition. l

A `piiictioal embodiment of the invention represented 'in thev accompanying drawings forming a part of this speeicati'on, in which similar characters of reference lnidicate corresponding parts in all the views.

A suitably constructed frame A is providedWitli-a-central opening B for the pasof a block C made of concrete, cement or other plastic material', the block being operated upon before it is'coinpletely set or in dried condition. The block is suspended by clamps D .from a. cross head E forming part of a -iloloclccarrier and feeder El for vuit-erinittently lowering 'the' block so that the saine can be severed into stones C", as

indicated in Fig 2, and as hereinafter more fully described. A series of pressure plates Specification of Letters Eatent. 191e, serial No. 575,710.

F are adapted to engage the block C with their pressuieedges, so as to ,completely enclrcle the block C. On moving the plates l? inward the pressure edges exert an .in-

ward pressure onw the block G along a line surroundingr the block C, -until the stone vC is severed 'from lthe block Gand drops ofl,

Athe severed faces of the stone and block appearing in a condition as if naturally 'broken (see Fig. 2).

The plates'lP at their pressure edges range in the saine plane,

from the center ot the opening B, in which cent-rally suspended, as

the slides G is provided Witha guideway by a bearing I in the .forni onaa. vertically-extending shaft J, .journaled in suitable hearings on the arranged on the inain. trame gconcentri- `cally with the opening B, and the said gear wheel K is in mesh with a pinion Lattached in the main frame a pulley L connected with other machinery for iinparting a continuous rotary motion to the shaft L. Now when the machine is running and the shaft L is rotated, then a rotary motion is .given by thepinioii L to the gear Wheel K, which iii turn rotates the several piiiions J2, thus turning the cams J A, and provided With main frame A. @n the upper end ot each cam shaft J is sein mesh with a gear Wheel, rn in suitable hearings A and the plates are bolted or otherwise secured to slides G, mounted `jtoslide lin suitable guideways H, arranged on the main frame A, the said slides G and their plates F moving readily toward and and thereby moving. the slides G simultane- I Ioli-sly. in direction in which the shaft L is turned.

vThus the several plates l5`--ai'e sini'ultaiie; 4ously advanced to engage their pressure edges with the sides of the block C, to sever a stone C from the said block, as before inentioned, and shown in Fig. 2. 4.

In order to permit accurate setting of adjustable in its guidevvay H, and for this with gear 'Wheels N 'ard or' outward,v according to the G 4is independently l other, one of the gear wheels having a handle N2, adapted to be taken hold of b v the operator4 for turning the gear wheels'N to revolve the screw rods N' and thus shift. the slide Gr and its plate F inward oroutward` to bring the pressure. edge of the plat'e l" into proper position relative to the hloclt C. It is understood that this adjustment is made when the machine is'aty a standstill, and the bearing I is 'held against-anoreinent by its cam J', so that on turning the screw rods N the slide G'rud its plate l." are moved inward or outward, according to the direction in which the screw rods N arc turned, by the operator `haviu hold of the Lhandle N2.

In order to permit aeeurgite.setting or adjusting of thejslides G and the plates l",

Scales O, representing linear'measurement are marked on the slidesG (see Fig. l). the marks on `the scales indicating' along` the outer edges olE the guideways ll, to enable the operator on turning the handle NJ to inove the corresponding slide Gr the desired distance inward or outward, as the ciretun, stances may require. As shown in the. drawings, the pressure plates F overlap, so that the device can be readily adjusted Jfor severing bloeltsvof tlitt'erent sizes and shapes.

The block carrier and' -feed E t'or intermittently lowering the hloclt C, at the time the slides G and thelr lnni'es F more outward, may he ot' any aplnoved construction, and, as shown, consists ot` a cross head E provided with hearings li2 for the passage of vertically-disposed screw rods l1, journaled in suitable bearings arranged on .the overhead structure A2 torniing part otE the frame A. The screw rods l are adapted to he engaged hy :half nuts Q, mounted to turnen pivots Q', arranged on' the top ot' the cross head E, and the said halt nuts Q, are normally heldin contact with ,the screw rods P hy springs QL" pressing; the said halt nuts rlhe halt' nuts Q are connected with chains R t-z-ttending,- inwardly and passing;l around pulleys R" journaled on top ol.' the cross' head l, the chains connecting with a chain It?, under the control of the operator,

for swinging thehaltE nuts Q out ol engagementwith the scriwrods il. whenever itis desired. to raise'the cross head ll" atfter a. block C has heen severed-into building' stones C by the successive action otthe' ltnivcs l?, as previously explained.

The upper' ends of the screw rods l) are provided with sprocket wheels l. coin neoted with veach other hy a` sprocket chain P2, and ,fon one of the screw rods l is secured fr pinion S in mesh with a mutilated gear wheel S', secured on the/upper end ot.' a shaft Lt, forming; an extension ot the driving shaft I/previously mentioned, so

that when the shaft L is rotated an' intermittentturningmovement is l'given' to the screw rods l. to intermittently lower the cross head ll. and consequently the clamp li a-nd the hloch' (l, atthe time the knives l" more outward away from the block C. During the time lthat the plates l? more in* ward in engagement with the hlocl C. the toothless portion ot the mutilated gear wheel b" is passing' the pinion S, so' that the latter remains at a standstill and consequcntl)Y the feedingy ot" the block C is suspended during;l the severine' operation ot' the struc t" from the liloclt C. then the last stone has been severed from the lloclt (l. the rotation of'the shaft. L is stopped, and then the operator pulls on the chain R2, so as to disengage the halt nuts t'roin the screw rods l. lVhen the haltI nuts are disengaged trein the screw rods ythe cross head E can then slide freely on the screw rods and is moved upward by 'the operator into upper-A most ]n sition,'aftcr which the operator rcleascs the chain lig, so as to allow' the springs Q to return the halt' nuts Q, with a View to rciingage the halt nuls with the .screw rods l and thcrcluY support the cross head ll in an uppermost position. new hloclt C now placed in position on the clamp D, ai"- ter whirl] the machine is again started up and the ahorc. dcscribeil operation is re peutcd. l

For square hleelis (l, a. pair otl plates It. may he used for severing the block into square stones, but in thiscase each plate l?" hasangular pressure cde'es'lt, as will he readily understood hy Fig.

with the result that the severed tacos appear in the saine condition as a fractured stone surfsice, and hence'the faces of the stones produeedroin the hloclts vary oneft'rom the other, and-hence when such.- st'ones. are used v it intermittently for forming the wall of a building or a house, the faade thereof is not monotonous, as is naturally the case in buildings or houses built of bricks or concrete blocks which are alilre on ltheir faces.
